It is narrated from Sayyiduna Jabir (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) saw people pollinating the date palms and asked: "What is the matter with the people?"
It was said: O Messenger of Allah, they are pollinating. He (peace and blessings be upon him) said: "There is no need for pollination," or he said: "I do not think pollination amounts to anything."
The narrator says: So the people left off pollinating, and as a result the people's dates turned out shis (poor and spoiled). Then the Messenger of Allah (peace and blessings be upon him) said: "I am neither a farmer nor an owner of date palms; pollinate them."
